蓝狐精子常温保存与低温保存的比较研究

Comparison of Preserving Blue Foxes Sperms between Normal and Low Temperature

为探讨行之有效的精液保存方法,提高狐人工授精技术的效率,对9只种公蓝狐的精液进行了常温保存与低温保存试验。结果表明,常温保存精液精子平均存活时间为26.2 h,平均生存指数为12.75;低温保存精液精子平均存活时间为40 h,平均生存指数为17.92。低温保存可以延长精子的体外存活时间。数据分析结果表明,低温保存生存指数与常温保存生存指数的比值与常温保存生存指数呈线性关系,即低温保存效果与精液品质呈正相关,精液品质越高,低温保存效果越好。

The sperms of nine male blue foxes were preserved under normal and low temperature in this experiment. The results showed that sperm＇s average survival time was 26.2 and average survival index was 12.75 under the normal temperature, the same indexes of low temperature were 40 and 17.92. So low temperature can prolong the survival time of sperm in vitro. By analyzing the dada of the experiment, the conclusion was drew that the higher quality of sperms is, the more efficient preservation under low temperature is.
